Functions

func ChangeRequiresRestart 

func ChangeRequiresRestart(from, to Configuration) bool

ChangeRequiresRestart returns true if updating the configuration requires a complete restart.

Types

type CommitResponse added in v0.11.9 

type CommitResponse struct {
	ValidationError error
	RequiresRestart bool
}

type Committer added in v0.11.9 

type Committer interface {
	VerifyConfiguration(from, to Configuration) error
	CommitConfiguration(from, to Configuration) (handled bool)
	String() string
}

The Committer interface is implemented by objects that need to know about or have a say in configuration changes.

When the configuration is about to be changed, VerifyConfiguration() is called for each subscribing object, with the old and new configuration. A nil error is returned if the new configuration is acceptable (i.e. does not contain any errors that would prevent it from being a valid config). Otherwise an error describing the problem is returned.

If any subscriber returns an error from VerifyConfiguration(), the configuration change is not committed and an error is returned to whoever tried to commit the broken config.

If all verification calls returns nil, CommitConfiguration() is called for each subscribing object. The callee returns true if the new configuration has been successfully applied, otherwise false. Any Commit() call returning false will result in a "restart needed" respone to the API/user. Note that the new configuration will still have been applied by those who were capable of doing so.
